Every LV package has a unique code, which is usually printed on the inside of the package and expressed in the form of serial number. This number is consistent with the number on the invoice and can be used to enjoy free care and maintenance in the specialty store.

But the information on the invoice is usually more detailed, including the date and place of purchase, store information and personal signature. Therefore, although LV bags and invoice codes are different, they both have their own unique information and functions.
